You used it already! (;-)

In this forum, you clicked on OS:Windows. You can select more than one OS
(->"multi" options or MOptions). The according configuration entry is:

MOptions OS = Linux, Windows, MaxOSX, All, Other

It's hard to tell the problem from what you report. Have you tried the latest
release http://midas.psi.ch/elog/download/windows/elog258-6.exe ? There were
some problems with the password file in 2.5.8 versions prior to patch level 6.

I added a paramet "case sensitive search" which does this. In addition, the
switch defines the default state of the "case sensitive" check box on the find
page. The new functionality will be contained in the next release.

Please send me your elogd.cfg configuration file.

How should elog remember that? If you put this into the URL like

http://<elog-host>/<logbook>/?exp=12&exp=14&exp=18

to expand the entries 12, 14 and 18, it might work fine. But imagine that some uses
have very long list with thousands of entries. This would make the URL very long,
everything very slow and could even crash some browsers.

What I usually do is to not expand the list. If I click on an individual entry, I
see then the expanded thread for that entry above that entry. But you probably
realized this possibility already.

Can you send me the part of your config files with those things so that I can
reproduce it?

Sounds like a good idea. Will put it on the wishlist.

The concept of a session ID is not present in elog, so implementing it would be harder
than writing elog from scratch. Keeping the thousand 'expansion' flags in cookies is bad
as well, because your browser will send them all each time you request a page, which can
then slow down things considerably over slow lines.
